PIVOTAL-SHACKLE PERMUTATION-PADLOCK.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed May 5, 1910. Serial No. 559,474.

To all whom it may concern:

Be it known that I, JOSEPH A. SIMIsKY, a citizen of the United States, residing. at Worcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Pivotal-Shackle Permutation-Padlocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in pivotal shackle permutation padlocks and comprises a simple and efficient device of this nature having various details of construction and combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a side elevation of my improved permutation padlock. Fig. 2 is a central longitudinal sectional view. Fig. 3 is a cross sectional view on line 3-3 of Fig. 2. Fig. 4 is a cross sectional view on line 4-4 of Fig. 2.. Fig. 5 is an enlarged detail perspective view of a part of the invention. Fig. 6 is a sectional View on line 6-6 of Fig. 2, and Fi .7 is a detail perspective view of the rotata le rod.

Reference now being had to thedetails of the drawings by letter, A designates the casing of the padlock which is provided with a socket opening B near one end adapted to receive a pawl G which is mounted upon a pin 0 in the recessed end of the shackle D, a spring D being interposed within said recess and adapted to hold the pawl at its limit in one direction and in which position it will automatically look when the shackle is in a closed relation. Said shackle is pivotally mounted upon a pin D upon the casing, a spring D? being provided which has one end embedded in the pivotal end of the shackle at one side of its pivot and its other end bearing against the clrcumference of the casing and servmg to normally throw the same to its farthest outer movement when released. The shank portion of said casing is hollow and is provided with a longitudinal slot E through which the tumbler member F is adapted to be moved to allow the shackle to be released. Mounted within the casing is a rod K reduced in diameter as at K to form a cam portion K Said rod has a concaved' proecting portion N at the inner end thereof which projectin portion is adapted, when the rod is in a locking relation, to engage and hold the spring-pressed pawl at the end of the shackle, but allowing the pawl to be released as a artial rotary movement is imparted to said rod. A spring E is fastened to the end wall of said socket within the casing and is adapted to frictionally engage and hold the pawl in a locked relation with the end of the rod. Said tumbler member has resilient concaved arms 0 pro jecting from the opposite ends thereof and adapted to embrace said rod, while the shank portion of the tumbler member is adapted to rest within the reduced portion of the rod and to be actuated by the cam portion K for the purpose of throwing the tumbler member outward or retracting the same within the casing as the rod is turned. It will be understood that the member F will be held within its retracted position when the various notches in the disks are out of registration with one another and that, when the notches are all in registration, the tumbler member may be thrown outward into the notches by a partial rotary movement imparted to the rod and which rotary movement of the rod will cause the projection N of the latter to pass out of enga ement with the pawl C and allow the shac le to spring open.

A coiled spring Q, is fastened at one end to the casing and its other end to the circumference of the rod and serves to return the rod to its'normal position after having been given a partial rotary movement to free the pawl from the rojecting end of the rod. A pin J projects rom said rod and is movable within a transverse slot I formed in the shank portion of said casing, said pin limiting the rotary movement of the rod. The spring Q, is adapted to normally hold the rod in a locked relation with the awl and is put under tension when the pin 1s thrown to the opposite end of the slot. A second and coiled spring, designated by letter R, is positioned between a shoulder upon the collar It and the outer inclined disk ring T and.

serves to hold the disk rings frictionally in contact with one another. Fixed to the end of the rod is a milled disk L aflording means whereby the rod may be rotated.

Mounted upon the cylindrical shank portion of the casing is a series of disk rings or" different diameters, designated those of smaller uniform diameters by letter T and each of the latter provided with a lug T projecting within its central aperture and adapted to engage a longitudinal groove T formed in the cylindrical casing upon which it is mounted and thereby held from rotation but allowed a sliding movement and the disks of larger diameters T which are rotatable, and upon each of said disks appear nu-- morals and each disk has a notch S formed in its inner edge, all of which notches must necessarily come into registration with one another and immediately opposite the tumbler member which is actuated by the cam portion of said rod in order to allow the rod to be axially rotated. Said disk rings T are held from rotation upon the casing with their notches in registration with one another, while the other disks T are rotatable and the notches of which must needs be brought into registration with the notches of the other disks in order to allow the rod to be rotated to release the shackle.

The operation of my invention will be readily understood and is as follows When the partsare in the positions shown in Fig. 2 of the drawings, the pawl at the end of the shackle is in a locking relation with the projecting portion N of the rod and in which relation, the end of the shackle as well as the end of the pawl are positioned within the opening in the casing. WVhen it is desired to unlock the shackle, it is necessary to rotate the various disk rings T in order to bring the notches therein into alinement, the disk rings T being held from rotation by the lugs T which are movable in the. groove T in the casing. Said rings T have numerals upon their circumferences whereby different combinations may be arranged. When all of the notches S are in registration, the rod having the cam portion may be given a partial rotary movement sufficient to cause the cam part to throw the tumbler member into'the various recesses of the disk rings and, as theprojecting end of the rod turns past the pawl, and the end of the shackle, the latter will be thrown out by the spring bearing against the pivotal end thereof. It will be noted that, when the rod is turned by means of the milled disk at the end thereof to release the shackle, the spring Q connected to the opposite end of the rod will be put under tension and serve to return the rod to its normal position after the milled disk is released and the padlock will be in position to be automatically looked as the free end of the shackle pushes the pawl into engagement with the projecting end of the rod.
